Prometheus was the son of Iapetus and the ocean nymph Clymene. He is often considered to be a good friend to mankind. When Zeus refused to give fire to man, Proemtheus stole it and gave it to them. He also cheated the gods out of the best meat during sacrifices. Prometheus was punished by the gods for giving man the gift of fire, and the sacrifice swindling. Many think he was chained there because he had a secret about Zeus, but would not tell. His punishment was to be chained to a rock on Mt. Caucasus, and have his liver eaten out by an eagle every day, then have it grow back every night. This was for eternity. In this image, Hercules has come to rescue him.
